Question

The sum of the deviations around the mean is

A) greater than zero if data are right-skewed.

B) smaller when the units are smaller (e.g., milligrams versus kilograms).

C) always zero.

D) dependent on the sample size.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
